RS-232
The AWS-3000 display can be connected to a printer, computer or data
collector via its RS232 interface. Every time a reading is accepted into
memory, a peak is cleared, or data is transmitted via the print data menu(s),
it is transmitted via the RS-232 port. To download the readings, go to the
DATA MENU.
SPECIAL NOTE: Model AWS-3000 PTEST is not equipped with memory, so the
operation of the RS-232 will vary from the standard unit. The protocol,
however, remains the same.
